Abstract

Спосіб починається з буріння свердловини від поверхні до основної маси підземного сланцю. Трубу вміщують в стовбур свердловини. У трубі створюють отвори в гідравлічному зв'язку з тріщинами в основній масі сланцю. Внутрішня поверхня щонайменше однієї секції труби покрита поглинаючою забруднювач речовиною. Рідину гідророзриву, що включає воду, пропанти і різні хімічні реагенти, закачують по трубі і в тріщини в основній масі сланцю. Рідина повторно входить в трубу з основної маси сланцю і переміщується до поверхні через секцію труби з покриттям, де забруднюючі речовини зв'язуються покриттям. Далі природний газ або нафта зі сланцю, що піддався розриву, надходить в трубу і пересувається до поверхні для відбору. Секція труби з покриттям залишається в землі постійно, так що зникає необхідність знешкодження поглинених забруднювачів. Як альтернатива, поглинаюча забруднювач речовина може бути нанесена на пропанти, які залишаються в тріщинах основної маси сланцю. Спосіб також може бути використаний в ситуаціях, не пов'язаних з видобутком газу або нафти, такого як витягування забруднюючих речовин з системи охолоджування ядерного реактора.The method begins with drilling a well from the surface to the bulk of the underground shale. The pipe is placed in the wellbore. The pipe creates openings in hydraulic connection with the cracks in the bulk of the shale. The inner surface of at least one section of the pipe is covered with a substance that absorbs the contaminant. Hydraulic fracturing fluid, including water, propane and various chemical reagents, is pumped through the pipe and into cracks in the bulk of the shale. The fluid re-enters the pipe from the bulk of the shale and moves to the surface through the coated section of the pipe where the contaminants bind to the coating. Further, natural gas or oil from the exposed shale enters the pipe and moves to the surface for selection. The coated pipe section remains in the ground permanently, so that the need to neutralize the absorbed pollutants is eliminated. Alternatively, the pollutant-absorbing substance may be applied to propane that remains in the fractures of the bulk of the shale. The method can also be used in situations other than gas or oil, such as the extraction of pollutants from a nuclear reactor cooling system.
